1 DOUBLE BLOCK AND BLEED VALVES

2 ENGINEERING - QUALITY AND TESTING Energy Valves is specialized in designing and manufacturing DBB valves (ball - plug - gate). Technical solutions and engineering are in accordance to American standards API / ASME / ASTM and every project is fully supported by test with Nastran (Finite Element Analysis solver) The simulation was carried out in accordance with Finite Element Methodology, the software used to solve the linear elastic equations is Nei Nastran v 10.0x64. Technical Report Machining Valves manufactured by Energy Valves are designed and produced in Italy, utilizing exclusively european know-how, materials and machining. Materials are certified in according to EN or 3.2 Forging Low Temperature Liquid Penetrant Fugitive emission Pressure Test Energy Valves believes in the importance of the final tests of the products. Dimensional and Functional Controls are carried out on every valve; Pressure Test is performed following internal procedures and API 6D API BS Prior to shipment the valves are tested on modern test benches, which will upon request issue detailed test diagrams.

3 Introduction DBB VALVES Long lasting safety and high performance are the characteristics on which is based the production of valves DBB, born from the need to support the demand for oil and gas industries that use complex system in offshore and onshore. Valves illustrated here are in fact installed by major oil companies in Asia and Europe. DBB Ball VALVES - Design Features - Floating or trunnion mounted - Full or reduced bore - Side entry or top entry design - Wafer body construction compact side entry - Firesafe - antistatic design and anti blowout stem - Soft or metal to metal seating - zero leakage - Bleed valve needle or ball type - Fugitive emission class B certificate - Very reduced dimensions and weight DBB Plug VALVES - Design Features - Lubricated and non lubricated valves - Metal to metal seating - zero leakage - Top entry - field repairable - Pressure balanced - lower torques - Full port or reduced port - Round port - low turbulence, pressure drop - Bleed valve needle or plug type - Firesafe - antistatic design and antiblowout stem - Wrench, bar handle, worm gear or actuator operated - Hard coated and treated with low friction ptfe/graphite coating to reduce friction coefficient and solves wedging problems KEY FEATURES FOR BALL AND PLUG VALVES - Size range: Ball 1/2 through 16, plug 1 through 12 - Pressure rating: asme 300 through asme 2500/API End connections: flanged - hubs - threated butt welding - Materials of construction: carbon steel - stainless steel - duplex - super duplex inconel - bronze - monel-compliance to nace MR standard last edition. - Standard customer requirements
